INTRODUCTION: The splenium of the corpus callosum has a specific structure of blood supply with a tendency towards blood-brain barrier breakdown, intramyelinic edema, and damage due to hypoxia or toxins. Signs and symptoms of reversible syndrome of the splenium of the corpus callosum typically include disorientation, confusion, impaired consciousness, and epileptic seizures. CASE REPORT: A previously healthy 32-year-old man suffered from weakness, headache, and fever. Subsequently, he developed apathy, ataxia, and inability to walk, and therefore was admitted to the hospital. Cerebrospinal fluid showed protein elevation (0.9 g/l) and pleocytosis (232/1 ul). A brain MRI showed hyperintense lesions in the middle of the corpus callosum. The patient was treated with antibiotics, and subsequently, in combination with steroids. Two months later, the hyperintense lesions in the splenium and the basal ganglia had disappeared. Almost seven months since his hospitalization in the Department of Neurology, the patient has returned to his previous employment. He now does not exhibit any mental changes, an optic edema and urological problems have improved. In addition, he is now actively engaged in sports. CONCLUSION: We have described a case of a 32-year-old man with confusion, ataxia, and inability to stand and walk. The man developed a febrile meningeal syndrome and a hyperintense lesion of the splenium, which lasted for two months. Neurological changes, optic nerve edema, and urinary retention have resolved over the course of seven months. We think that the prolonged but transient lesion of the splenium may have been caused by encephalitis of viral origin. and A. Meleková, L. Andrlová, P. Král, L. Ungermann, E. Ehler
Cíl: Hlavním cílem studie je popsat transverzální a longitudinální mobilitu nervus medianus u pacientů se syndromem karpálního tunelu před otevřenou dekompresí karpálního tunelu a s odstupem po ní. Materiál a metodika: V období od března 2007 do června 2009 bylo do studie zahrnuto celkem 72 pacientů se syndromem karpálního tunelu. Vyšetření pohybu nervu bylo provedeno neinvazivně pomocí ultrazvuku před operací a několik měsíců po operaci. Transverzální pohyb byl měřen v úrovni os pisiforme a podélný pohyb byl měřen na volární straně předloktí ve vzdálenosti 8–11 cm proximálně od zápěstí. Dekomprese karpálního tunelu byla provedena standardní otevřenou technikou. Výsledky: Průměrná transverzální amplituda nervu byla v našem vzorku 1,82 mm předoperačně a 1,76 mm pooperačně a rozdíly nebyly statisticky významné (p > 0,05). Průměrná amplituda longitudinálního pohybu nervus medianus byla 3,74 mm předoperačně a 3,89 mm pooperačně a rozdíl nebylo možno hodnotit jako statisticky významný (p > 0,05). Závěr: Po otevřené dekompresi karpálního tunelu nedochází ke statisticky významným změnám v transverzální a ani v longitudinální mobilitě nervus medianus. Otevřená dekomprese u pacientů se syndromem karpálního tunelu nemá vliv na schopnost nervus medianus přizpůsobovat se pohybu okolních struktur., Aim: The main objective of the study was to describe transverse and longitudinal movement of the median nerve in patients with the carpal tunnel syndrome before and with delay after open decompression of the carpal tunnel. Materials and Methods: From March 2007 to July 2009, the study enrolled a total of 72 patients with the carpal tunnel syndrome. The examination of nerve movement was performed noninvasively by ultrasound before and several months after the surgery. Transverse nerve amplitude was measured at the level of the pisiform bone. Longitudinal movement was measured on the forearm at a distance of 8–11 cm proximal to the wrist. The standard open surgery was performed. Results: The mean of maximum transverse amplitude of the median nerve in our sample was 1.82 mm preoperatively and 1.76 mm postoperatively, and the difference was not statistically significant (p > 0.05). The average amplitude of the longitudinal movement of the median nerve was 3.74 mm preoperatively and 3.89 mm postoperatively, and the difference was not considered statistically significant (p > 0.05). Conclusions: There were no statistically significant changes in transverse or longitudinal movement of the median nerve after open carpal tunnel decompression. Open decompression does not affect biomechanical parameters of the median nerve in carpal tunnel syndrome patients.
